Earlier this month, it was reported that The Mayor of Castro Street producers Neil Meron and Craig Zadan said their Bryan Singer-directed film on gay rights activist Harvey Milk would be shot after Singer finishes filming Valkyrie. Not so fast, say the folks working on the Superman Returns sequel.

“That’s total horse sh*t,” said a source within Singer’s camp for IESB.net. “I would say the same thing if I was producing that film but don’t you realize that most of the ‘Superman’ producers are working with Bryan on ‘Valkyrie’? Gil Adler and Chris Lee both are in Germany with Bryan and I can guarantee you that there is some work being done with ‘Superman’ right now.”

The current plan is to start shooting the Superman Returns sequel by the summer of 2008.
